How many records would it take to fit all this?
There is a 3 record set being released. According to Amazon it contains: 20th Anniversary 3LP Edition of the unwitting swansong of the single most influential band of the 1990s, features the original album remastered at Abbey Road Studios on 2 LPs and for the first time available at high fidelity 45 RPM, plus a 33 1/3 RPM LP of all the remastered B-sides, never-before-heard mixes and bonus tracks from the original album release. All 3 LPs are on 180 gram vinyl.

Big Nirvana fan, but I'll admit that I'm a little sad. I was hoping they were held back one more never before heard song. new mixes/demos are okay ...i guess :( Also would have been cool to put You Know Youre Right on this release too so I didn't have to pick up the lame greatest hits album. That cover of Seasons In the Sun they had on the DVD of the box set would have been great too. Man, opportunity wasted. Guess I'll wait until the 50th anniversary
